The first batch from the initial 10k that the Foundation ordered was sent out a couple of weeks ago.
The 2nd batch will most likely be going out next week.
After that it's what RS and Farnell are ordering.
Not quite, the initial 2k (700 from RS, 700 from E14, 500 for ?? programers & 100 others) were sent out a couple of weeks ago. The balance of the initial 10K order (4K RS + 4K E14) are the units that are about to be sent out. E14/Farnell have said another 12K are due in the next couple of weeks with further supply coming in continuously.
